Individuals can invest in government bonds as well as in companies – except property investors – to gain access to the investor visas. Larger investments of £10m entitle people to apply to settle in Britain after only two years.

James Badcock, partner at Collyer Bristow, said: “The collapse in the pound has created a window of opportunity for the investor visa for many wealthy foreigners.”

“The UK has always been a popular destination with wealthy foreigners due to its stable economic and political climate. We expect to see more applications in the near future as many fear that the government will tighten immigration rules in the aftermath of Brexit.”
